Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00077 | $0.01779 |
| Opus 5.5 | $0.00031 | $0.00712 |
| Sonnet 5.5 | $0.00015 | $0.00356 |
| Haiku 4.5 | $0.00008 | $0.00178 |
Grade A, and why
information-architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Information Architect
Make complex products feel simple by giving users a consistent mental model: clear hierarchy, stable navigation, predictable labels, and strong wayfinding.
This skill is for designing the structure (what goes where and why). Pair with frontend-design when you also need a UI/visual redesign.
Quick Start (do this first)
- Ask up to 5 questions:
- Who are the primary users and their top 3 jobs-to-be-done (and what must feel “easy”)?
- What surface is this (web app, marketing site, docs/KB, mobile app)? Any SEO, i18n, or accessibility constraints?
- What exists today (current nav/sitemap), what’s broken, and what must not change?
- What are the “things” in the system (entities/content types) and what are the “actions” users do to/with them?
- Any hard constraints: permissions/roles, compliance, product strategy, roadmap, or analytics targets?
- Choose one primary organizing principle (one “north star”):
- task-first, object-first, lifecycle-based, audience-based, or frequency-based (see
references/ia-models-and-principles.md)
- Produce the minimum set of IA artifacts (in this order):
- IA thesis (1–2 sentences): the organizing logic + how users will find things
- Map: sitemap/app map (
SITEMAP.mmd; template inassets/ia-docs/) - Navigation spec: global + local + contextual nav rules (
NAVIGATION.md; template inassets/ia-docs/) - Labeling & naming rules: consistent labels, verbs/nouns, capitalization (
references/labeling-and-microcopy.md) - Taxonomy/metadata (only if needed): tags/facets + ownership rules (
TAXONOMY.csv; template inassets/ia-docs/)
Guardrails (utmost simplicity)
- Prefer fewer, clearer choices over “complete” categorization. Users scan; they don’t read.
- Keep top-level navigation small and stable. If everything is top-level, nothing is.
- Don’t mix organizing principles at the same level (e.g., “By Team” next to “Settings” next to “Reports”).
- Avoid duplicate pathways unless the user benefit is explicit (and labeled consistently).
- Use progressive disclosure: reveal complexity when it becomes relevant; keep early steps lightweight.
- Names are UX: labels must match user language, not org structure or internal terminology.
- Optimize for wayfinding: users should always know where they are, what’s here, and what’s next.
- When in doubt, scan
references/anti-patterns.mdand delete complexity.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 126 lines · 77 tokens per session scan A 128f4515e36f
information-architect is a skill published in the GitHub repository vadimcomanescu/codex-skills (25 stars, last pushed 9mo ago), licensed MIT. It adds 77 tokens to every session and 1,779 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
